I guess my preference would be CILK_SIMD tree (handled the same as OMP_SIMD during genericization/instantiation), and let gimplification turn that into (note CILKSIMD added, and everything reordered): GF_OMP_FOR_KIND_FOR 0 << 0 #pragma omp for GF_OMP_FOR_KIND_DISTRIBUTE 1 << 0 #pragma omp distribute GF_OMP_FOR_KIND_SIMD 2 << 0 #pragma omp simd GF_OMP_FOR_KIND_CILKSIMD 3 << 0 #pragma simd This way, when testing for whether it is any kind of simd we can use gimple_omp_for_kind (stmt) & GF_OMP_FOR_KIND_SIMD instead of the current gimple_omp_for_kind (stmt) == GF_OMP_FOR_KIND_SIMD test, and the equality can be tested where we expect differences (say, in the diagnostics - provide different wording), or in nesting restrictions/combined constructs etc.
I have done as suggested, and cleaned things up along the way.I believe this is the last remaining TODO on my Cilk Plus pragma simd list. Everything else is dependent on OMP4.
Is this what you had in mind?If you'd like, I can submit the OMP changes separately so we can put them on the OMP4 branch. However, my plan is to start pushing the OMP4 supporting bits (from gomp-4_0-branch) and the Cilk Plus #pragma simd support (from aldyh/cilk-in-gomp) next week, so perhaps everything will fall into place shortly. As you wish...
